Beta release, not fully tested yet. Some major changes at settings class, so complete reconfiguration of complete network and device settings is needed, if you update from older version. Improvements:

• Handling of sluggish devices improved. Tested with ME102H and should improve also device ME81H - please test. Thanks to @J-rethinkmx, who provided his code that handles MCU device communication better. Now changes at device parameters immediately reflects in a MQTT status update - at least at ME102H it's now working perfectly.
• Settings were reorganized and should save some EEPROM space. Basically Strings and byte arrays are now stored with variable length. EEPROM write accesses were also reduced.
